We need to be extremely careful with auth ports since leaking them into
subprocesses may expose a root-auth port to non-root processes.
Notably, get_nonsugid_ids was caching it, thus preventing glibc's exec
implementation from dropping it. Login is also reimplementing hurdexec
but without all the cloexec logic.
This commit fixes various auth leaks.

* configure.in: Check for _hurd_exec_paths.
* utils/fakeauth.c: Call _hurd_exec_paths instead of
_hurd_exec if it's available.
* utils/shd.c: Likewise.
* utils/rpctrace.c: Get prefixed_name from file_name_path_lookup and pass it to
_hurd_exec_paths instead of calling _hurd_exec.

Our variants print stack traces on failures. This will make locating
errors much easier.

Some calls to `error', `printk', and `problem' lacked a format
string, leading to build failure when compiling with stricter CFLAGS.
* nfs/mount.c (mount_root): Add format string for `error' calls which
lacked it.
